Fever is a common clinical symptom, and fever is often accompanied by body aches and pains, both of which are often common clinical manifestations of upper respiratory tract infections. Firstly, fever is usually caused by bacterial or viral infections, which produce toxins that act on the body and produce generalized aches and pains due to the proliferation of bacteria or viruses in the body. Secondly, because of the increase in body temperature, the metabolism of the body is accelerated, which causes the accumulation of acidic metabolites in the body and causes generalized muscle aches and pains and weakness. In addition, the body produces pain-causing substances such as prostaglandins during fever, which can also cause pain in the whole body and joints and muscles. For this situation, first of all, we should understand the cause of the fever, and then first use physical cooling, such as cold towels on the forehead or wipe the body with alcohol, drink more hot water when the fever, do not spicy, if necessary, oral antipyretic drugs. Usually exercise more to enhance the immunity of the body. Fever is actually a self-protective measure of the organism. The whole body aches and pains during fever are the same as the muscle aches and pains caused by strenuous exercise, mostly due to accelerated metabolism and excessive lactic acid production. When such a condition occurs, timely symptomatic treatment is sufficient. Commonly used aminogalactam capsules or compound aminogalactam can effectively relieve fever and body aches and pains. For specific medication and dosage, you should go to the hospital for a face-to-face consultation and use the medication under the guidance of a doctor.
